✈️ I'm David — the airfare code-breaker. For 15 years I’ve engineered booking systems, scaled OTAs in 25 countries, and personally overseen 3 million+ ticket sales worth $1.2 B. After watching travelers pay $150 or $500 for the same seat, I reverse-engineered the pricing algorithms and turned the findings into this guide. Why listen to me? Built & sold a leading flight-tech startup (exit $32 M) Trained airline and OTA teams across Europe & Asia Strategies battle-tested on real bookings, not blog theory Average student saves $200-$500 per trip My mission: help digital nomads and everyday flyers outsmart the fare engines and keep more money for adventures.
